lde it known th at I, PET R COOPE- R HEWITT, a citizen of. the United'fi tates, and a resident of New 3 deli, county of ElewYork, State of New York, have inventedeertain new and useful Improvements in Aerial Radiating: Circuits, of which the following is a specification.

My invention relates to certain improvements in the construction, organization and methodof operation of wireless telegraphy and kindred apparatus. li'eretofore' it has been customary to employ as a radiating circuit some form of extended conductor usually projected into the air from which the energy is radiated in the form of electric waves, such extended conductor being repeatedly charged with high electrical otentia-ls.

tribution in space of the lines or generating conductor or My invention re ates particularly to 8;, novel form of radiating circuit. While the usual forni termined, yet it seems probable that the waves of electric potentials to which the conductor issubjected, pro'ect into space waves which may be due to the magnetic field established in the neighborhood of the conductorby the electric currents in the conductor. The direction ofsuch magnetic field induced by a vertical conductor would be in e horizontal plane, and the distribution of the resultant Waves of stress would then be such as would result from such .field ri- .marily generated in a horizontal direction.

More generally stated, any straight wire, whatever its direction, when energized by oscillatory currents of a time period equal-to the natural time period of said wire, generates afield of force whose me netic lines lie in planes perpenzhcular'to saicl wire, the electrostatic lines lyins; at right; angles to the magnetic lines, in planes substantially radial The direction and length of such wire determine the direction and diselectrostatic lines as straight longitudinal of the wire.

One of the secure'a field of force having primarily a direction such that the direction and space distrihution of the magnetic and electrostatic force with respect to the length of the radiator, are reversed so that the magnetic lines extend the Specification of Letters l etent,

Ion th best ads ted for radiation me be purposes of my invention is to en.tire len di of the radiator in the mow-l planes passing thr o of the radiator, while elect-lee tend to lie in planes at right of the radiator. By my .ai magnetic end electrostatic lines, with respect to the longitudinal exisradistor, are substantially right eiigl'es those which would be generated by a t wire located at and extenfing axis.

- The. general plan of'my invention is to 5 vide any suitablesys'tem ofprinie y ing circuit withe radiating" circuitcon ing a series of two croncre coils or sole s hstving a common and preferably posed in a vertical direction. These m connected in multiple and so pro ortion to produce a resulting vertical nc of netization adapted to radiate. proper tioningthe length of the field created the solenoids to the time of vsriation the true 4- obtained. In some {asses it may be to arrange the series in some other direc usually ireier to l then a vertical, but it the solenoids so arranged. that the or each is an extension of the exis oi' the o? I prefer to employ a co coils so that the electro static lines will be sufli space thereby insuring efiicieut roulette pro agation thereof.

the solenoids ell lieing e. ranged in a Vertical line. llurrents tmx crsr the Vertical conouted through the doctors will then on dist-r several solenoids and cause resultant magnetic field ex tending axially through the scv ersl solenoids, with the consequent aerial i. dia'tion. The sever-cl coils are so proportioned with reference to each other that they will severally receive their proper currents, and will vibrate substantially synchronously, in proper phase to produce the resultant rspidly varying magnetic field or flux.

The coils are here shown each having one terminal connected with one of tlie vertical conductors 13, While the other vertical co'nd actor I l, connected with on interme diets point 16.
